Characterization of the physiological state of fungi by dynamics of colony emergence on solid media

Poisson distribution was shown to be applicable to the dynamics of emergence of fungal colonies on plates inoculated with pure cultures or environmental samples, indicating the possibility for application of Hattori approach for assessment of the physiological state of fungi. The differences in physiological activity of different fungal species and genera, between spores and mycelia, or between the fungal populations from different environments, were revealed using the t r (delay time for colony emergence) and λ (potential capacity for growth) parameters.
